I'm sure Winoweenie, KC and others will have some recs for you. Sterling is interesting for the gondola ride up to the top and Moorish architecture, etc. I think Beringer's has a pretty educational tour. Some like the wineries along the Silverado Trail but I have not been there. Be aware that most tastings in Napa are pricy. If I return to Napa I think I will book on the Napa Valley Wine Train http://winetrain.com/

I can probably get the VIP tasting set up for you at Duckhorn. Dan is a friend of mine. Also the same at Flora Springs. You didn't say when you'll be there and for how long. If interested let me know. WW

I'm leaving this thursday morning and staying through mid-day Sunday. I have a couple of meetings set up already, but anything you'd be willing to help out with would make me eternally grateful. If you feel like it, shoot me an email eads.david@gmail.com so it's a little easier to discuss. Thanks.
